| Abstract(in English) | An electroabsorption modulator (EAM) integrated with a laser diode is key device of a low-power consumption and low cost optical transmitter for middle-distance optical communication. Reduction of the modulation voltage (V_m) of an EAM is an important issue to further reduce the power consumption of the transmitter. We have developed an Mach-Zenhder (MZ) interferometer-type EAM (MZEA) that has large extinction ratio (ER) since it modulates the light intensity by both optical absorption and interferometric extinction, resulting in low-voltage operation for a given ER. Furthermore, we integrated the MZEA with a DFB laser diode and obtained low V_m operation with comparable output power to a conventional EAM integrated with a DFB laser diode. |
